The Current Clamp aids in measuring AC or DC current flow through

a wire or cable.

Safety Precautions

Do not

operate this tool before reading these instructions in their

entirety. The following guidelines must be followed to avoid accidents

that can result in electric shock or personal injury.

■ Pay close attention to WARNING stamped on the tool’s case.

This warning, as well as all warnings and precautions used through

out these instructions, must be followed to avoid electric shock

and/or personal injury.

■ The RESPONSIBLE PARTY shall be made aware that, if the equip-

ment is used in a manner not specified by the manufacturer, the pro-

tection provided by the equipment may be impaired.

■ Before using this tool, verify its proper operation on a known similar

function source where the unit value is also known. Take corrective

action based on the indicated results.

To prevent electrical shock and/or damage to the tool or the equipment

under test, observe the following safety precautions:

■ DO NOT apply more than the rated voltage, as marked on the tool and

tester, between terminals or between any terminal and earth ground.

■ Use caution when working above 30V AC rms, 42 V peak, or 60 V

DC. Such voltages pose a shock hazard.

■ To avoid false readings that could lead to possible electric shock or

personal injury, replace the batteries as soon as the low battery indi-

cator lights.

■ Always inspect the test leads prior to every use. If any damage is

found, do not use the tool.

■ Always consider electrical and electronic equipment to be ener-

gized (live). Never assume any equipment is de-energized.

■ Never ground yourself when taking electrical measurements. Isolate

yourself from ground by using dry rubber insulating mats to cover all

exposed/grounded metal. Stand on rubber mats and wear dry clothing.

■ Use one hand, instead of two, whenever possible to take measure-

ments. If two hands must be used, use extreme caution not to con-

tact any energized conductors with your hands. Be certain test

leads are dry and clean.

■ Do not hold the tool beyond the hand grip when taking measure-

ments.

■ Don't become part of the circuit. Think safety. Act safely.

If working on a vehicle, take the following added precautions:

■ Only work on vehicle in a well ventilated area.

■ Always wear safety eye protection.

■ Avoid moving fan blades or any potentially moving parts.

■ Avoid hot engine parts.

■ Put transmission in "park" (automatic transmission vehicles) or

"neutral" (manual transmission vehicles). Set the parking brake.

■ Turn the ignition "off" before connecting or disconnecting any test-

ing equipment.

■ Put blocks on drive wheels.

■ Avoid wearing loose clothing or jewelry when working on a vehicle.

■ Read your vehicle's service manual and follow it's safety proce-

dures.

SPECIFICATIONS

General

■ Captured Conductor Size: 0.75 in. (19mm) maximum

humidity

■ Storage Temperature: -4 F to 158 F (-20C to 70C), 80% relative

humidity

■ Battery Type: 9V DC, NEDA 1604, 6F22, 006P

■ Dimensions:

■ Lead: Coil cable with straight banana plug or 36-inch (91cm) test

lead clipped together

Electrical [at 73±9 F (23±5 C) 70% relative humidity maximum]

■ Effective Measurement Range:

10mV/1A: 100mA to 20A DC or RMS AC for 200mV range of the

tester.

1mV/1A: 1A to 200A DC or RMS AC for 200mV range of the multi-

meter.

200A to 600A DC or RMS AC for 2V range of the multimeter.

■ Accuracy

System accuracy: Current clamp accuracy + tester accuracy

For example, if the measured conductor carries a 1A current, set

the Current Clamp to 10mV/1A range to get an output signal of

10mV. Suppose the accuracy of the units is 1.5%, the tolerance

limit should be between 10.15mV maximum and 9.85mV mini-

mum.

When the unit is connected to a tester with an accuracy of 0.5% in

200mV range, the reading displayed on the tester will be 10.20mV

max. (10.15mV × (1+0.5%) = 10.20mV) and 9.80mV min.(9.85mV

× (1-0.5%) = 9.80mV)

■ Current Clamp Accuracy

DCA range = 10mV/1A: ±(1.5%+50mA) 100mA~20A

DCA range = 1mV/1A: ±(2.0%+0.5A) 1A~200A; ±(2.5%+5A)

200A~600A

ACA range = 10mV/1A: ±(2.0%+50mA) 100mA~20A

(40Hz~400Hz)

ACA range = 1mV/1A: ±(2.5%+0.5A) 1A~200A (40Hz~400Hz);

±(3.0%+5A) 200A~600A (40Hz~400Hz)

■ Load Resistance: 10KΩ typical

■ Temperature Coefficient: 0.1×(specified accuracy) Per degree C.
